Php 贝宝RESTAPI执行错误

我试图在Wordpress主题中实现PayPal支付。 我获取令牌，创建付款，将用户重定向到approval链接，获得用户的批准，但由于某些原因，我无法执行付款“curl响应为空

下面是代码（我仔细检查了executeURL和令牌，它们是正确的）

当您从批准url返回时，以前存储的令牌和执行url信息将丢失。它将变为空。您需要将其存储在cookie或数据库表中，并在返回站点执行时检索它

请检查此答案，这与您问的问题类似。curl verbose开关会给你？任何响应头？你能发布执行url吗？@lib 4-这种情况包括缺少头-我已经为answer@adyvcurl没有响应，这是执行url

if (isset($_GET['token']) && isset($_GET['PayerID']) ){
   $received_token     =   sanitize_text_field ( $_GET['token'] );
   $received_payerId   =   sanitize_text_field ( $_GET['PayerID'] );
   $execute_urls       =   get_option('paypal_processing');
   $payment_execute_url=   $execute_urls[$current_user->ID];
   $execute_urls[$current_user->ID]    =   '';
   update_option('paypal_processing',$execute_urls);

   $payment_execute = array(
    'payer_id' => $received_payerId
       );
   $json = json_encode($payment_execute);

   $json_resp = make_post_call($payment_execute_url, $json,$received_token);
   print_r($json_resp);
   echo "Payment Execute processed " . $json_resp['id'] ." with state '".    $json_resp['state']."'";
   }





 function make_post_call($url, $postdata,$token) {
    $curl = curl_init($url); 
    curl_setopt($curl, CURLOPT_POST, true);
    curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($curl, CURLOPT_HEADER, false);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($curl, CURLOPT_HTTPHEADER, array(
            'Authorization: Bearer '.$token,
            'Accept: application/json',
            'Content-Type: application/json'
            ));

    curl_setopt($curl, CURLOPT_POSTFIELDS, $postdata); 
    #curl_setopt($curl, CURLOPT_VERBOSE, TRUE);
    $response = curl_exec( $curl );
    if (empty($response)) {
       // some kind of an error happened
           print 'curl error';
       curl_close($curl); // close cURL handler
     } else {
     $info = curl_getinfo($curl);
        //  echo "Time took: " . $info['total_time']*1000 . "ms\n";
    curl_close($curl); // close cURL handler
    if($info['http_code'] != 200 && $info['http_code'] != 201 ) {
        //echo "Received error: " . $info['http_code']. "\n";
        //echo "Raw response:".$response."\n";
        exit('paypal error');
     }
  }

     // Convert the result from JSON format to a PHP array 
    $jsonResponse = json_decode($response, TRUE);
    return $jsonResponse;
     }
